The enstatite chondrites

Geochimica et Cosmochimica Acta, 1966
Abstract Fifteen enstatite chondrites have been recognized: Abee, Adhi Kot, Atlanta, Bethune, Blithfield, Daniel's Kuil, Hvittis, Indarch, Jajh deh Kot Lalu, Khairpur, Kota-Kota, Pillistfer, St. Mark's, Saint-Sauveur and Ufana. Their essential minerals are enstatite and/or clinoenstatite (40–60%), kamacite (20–28%), troilite (7–15%), and sometimes ...

Chondritic Earth Model

Nature, 1964
GEOCHEMISTS have frequently used the abundances of elements in meteorites as a guide to the overall composition of the Earth. The abundances in the chondritic meteorites have been commonly used on the assumption that they represent the closest approach to the composition, for the non-volatile elements, of the primitive unfractionated material in the ...

CO3 Chondrites: Metamorphic Sequence and Interclassification with Ordinary Chondrites

2005
Metamorphic grade of 7 CO chondrites is determined based on structural order of the Organic Matter. Petrographic types are attempted by interclassification with ordinary chondrites and are confronted with petrographic tracers.
